Abstract
The invention relates to manufacturing technique of optical lens, particularly the filming and molding technique of combined optical lens. The invention is characterized in that while injecting plastic, the agglutination of two optical lenses is finished and another optical lens is formed in the cavity of the die, that is, a negative pressure gas circuit is introduced into to the assembly of a dieplate insert matching with the optical lens, a static die plate and a protective plate, which means the optical lenses to be agglutinated are positioned by negative pressure generated when vacuumizing. The other side of the optical lens and one side of a punch insert together form the mould cavity of another optical lens. When injecting plastic, the mould cavity is filled with melted thermoplastic plastics and is agglutinated to the original optical lens under the help of the temperature and the high pressure when injecting plastic. Based on the method, three or more optical lens can be agglutinated and produced, greatly improving production efficiency and simplifying process, and effectively avoiding that the optical lens are easy to mildew and rot because of the bonds.

B, closed quiet, dynamic model utilize bonded optical lens to be formed the die cavity of another sheet optical lens by the one side of the punch insert in sticking face and the dynamic model;
C, continuation realize the operation of injection, preformed, cooling, pressurize, die sinking, stripping process.
It is radial that gas circuit on the said backplate (1) is arranged to donut, and the pore on the die plate insert (3) is also pressed concentric circles circumference layout accordingly; Said negative pressure line is led to three-way pipe by vavuum pump and is communicated with left and right sides valve respectively, has three-way pipe to lead to backplate (1) gas circuit between every group of valve.
Time-delay setting turn-off time of the time relay sj in the said negative pressure line electrical control circuit should be after the action of preformed operation.
Advantage of the present invention is without adhesive, and the thermoplastic during directly with injection moulding carries out on mould injection moulding as adhesive to be finished.Can one go out two, one and go out a plurality of optical lenses such as three, four, five, six.So the production efficiency height, technology is simple, and bond site can not produce mildew and rot denaturalization phenomenon.

The specific embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2,1-backplate, the quiet template of 2-, 3-die plate insert.The mould that adopts when this is injection moulding.
With reference to Fig. 3, be a constitutional diagram when two optical lenses.1-backplate, the quiet template of 2-, 3-die plate insert, 4-sealing ring, 5-gas circuit, 6-gas circuit.
With reference to Fig. 4, be a figure of backplate gas path layout when two optical lenses.Gas circuit is the radial layout of donut.
With reference to Fig. 6,7 are quiet formwork structure figure when two optical lenses.
With reference to Fig. 8, the 9th, gas circuit hole arrangement figure on the die plate insert.Pore also is concentric circles circumference layout.
With reference to Figure 10 is negative pressure line figure.Find out among the figure that below vavuum pump is positioned at, be communicated with left and right sides valve respectively by three-way pipe, two on left valve, right valve also are two, valve sets has three-way pipe to be connected therebetween and leads to the backplate gas circuit.
With reference to Figure 11, be that the negative pressure line electric appliance circuits is provided with situation.Switch HK among the figure, normally closed switch TA, normal open switch QA, time relay sj, C are coils, are one group of normally closed switch and one group of normal open switch above the valve one, two.The present invention's innovative point is introduced the negative pressure gas circuit in using the die plate insert that matches with a slice optical lens and quiet template, backplate assembly, the negative pressure that produces when utilization vacuumizes is located should bonding optical lens, and utilizes the one side of the another side of this eyeglass and protruding (recessed) core rod to form the die cavity of another sheet optical lens.When injection moulding, when this die cavity was filled the thermoplastic of molten condition, the temperature and pressure when utilizing injection moulding was bonded together with former optical lens, in like manner utilizes this way, can process the bonding of three above lens and produce.
The key step of this technology is to install the combined optical lens injection mold on injection machine, after the good every injection parameters of debugging, and separately quiet, dynamic model; With bonded optical lens after surface treatment, with hand or manipulator clamping and put into the die plate insert 3 that is contained on the quiet template 2, this moment the normally open contact QA in the closed negative pressure line electric appliance circuits, time relay sj work, start valve two, connect vacuum system, produce negative pressure, will accurately locate in the bonded optical lens inspiration die plate insert 3; Closed quiet, dynamic model utilizes bonded optical lens to be formed the die cavity of another sheet optical lens by the one side of the punch insert in sticking face and the dynamic model; Continue to realize the operation of injection, preformed, cooling, pressurize, die sinking, stripping process; It is radial that gas circuit on the backplate 1 is arranged to donut, and the pore on the die plate insert 3 is also pressed concentric circles circumference layout accordingly; Negative pressure line is led to three-way pipe by vavuum pump and is communicated with left and right sides valve respectively, has three-way pipe to lead to backplate 1 gas circuit between every group of valve.
